Samsung Oven - APIs for setting cooking mode / setpoint / cooking time

[nayelyz (SmartThings Developer Support)]

Sorry for the delay.
About capabilities in “proposed” state, this is the description provided by the engineering team:

Mutable, should be supported in APIs but considered beta bugs can happen. Use at your own risk.

Also, something to consider is that OCF devices such as Ovens work at a Plugin level (ST app), not the API level. This means that depending on the configuration of the device controller, not all the info is saved in the API and commands received from there might bring unexpected results.
In this post I shared more info about the functionality:

Get info from API

Welcome to the SmartThings Community, @Sdahl1234! This is the information we have so far by analyzing Jacob’s case. The team checked the profile assigned to the device (list of capabilities used), and they noticed the temperature and the other values are not available. They’re trying to investigate more about the root cause. More details To attempt to shed light on why some capabilities might show up in the ST app but not on the API side, the team shared these details: The phone client (ST app) uses OCF’s COAP protocol, which allows the physical device to define its resources (such as the temperature values). So, these values can be written there by the device and as a result, they can be displayed by the app. The APIs do not work via OCF, but, the profile is the manifest of what val…

TL;DR:
You can use the proposed capabilities but they might not work as you expect. OCF devices work best using them from the ST app. The team is aware of the requirement for an improvement of their functionality, there’s no more info so far.
